As humans living here in the city, we have gotten a little far away from our roots. This is way I am proposing a test project called Greenwalks. These green walks are normal city side walk that have had a layer of artificial grass laid upon and fused to them. Now this grass is not just cheap and tacky Astroturf, The Greenwalks will be composed of millions of little soft nanotube grass blades made from one of the most abundant elements in the universe, carbon. This grass will be designed to feel just like the front lawns and parks of your childhood which, will hopefully make for a happier city.
One of the big downsides of reel grass is its ability to hinder the progress of wheeled machines, like bicycles and strollers. The GreenWalks are not composed of normal crass though. When a section of the nanotube grass senses the curvature of a wheel it will automatically lay down flat to provide a smooth ride. Also, sense the artificial grass is networked and controlled by a cloud computer made up by thousands of processors embedded under and grass, any section of the grass can communicate to another section so that if a wheel is sensed in one section, the section following it will also lay down in preparation for the wheel. In the future these Greenwalks should give the city a little injection of green to combat the mixed tones of gray and makes up so many cites.
